Teachers of 9 and 10 year olds were found to use varied versions of lessons that increase conceptual understanding. Their effectiveness in supporting conceptual understanding was compared experimentally. Findings and implications for science teaching are discussed. (Author/DKM)

In this study a distinction is made between routine, semiroutine, and nonroutine problems based on the problem solver's knowledge. Routine problems are solved by applying a known procedure, semiroutine problems require planning that uses functional knowledge, and nonroutine problems require generation of new functional knowledge. Nonroutine…

Examines knowledge, its origin, the factors affecting its growth, individual and group differences, and the implications of these ideas for the teaching of science. Describes a model of learning as a conceptual change which might reconcile competing instructional frameworks so that "western science" could be taught effectively in…

The relationship of cognitive development to learning science is considered. Views of thinking from both a psychological and a scientific standpoint are compared in order to shed light on current science teaching practice. Metacognition and problem solving are discussed. (Author/MT)

Explores the extent to which student questions are indicative of understanding as well as strategies for encouraging questioning. Student questions are categorized as consolidation questions, exploratory questions, and elaboration questions. (DDR)

Investigated the nature of biology teachers' global content understandings, and sources and formation of subject matter structures (SMSs). Reports that the initial formation of SMSs was credited to college content courses and modified by the act of teaching. Variables that differentially affected SMS translation included teacher intentions,…

Investigates the effects of Science-Technology-Society instruction on a group of Taiwanese female 10th grade students' cognitive structure outcomes. Examines the role of student scientific epistemological beliefs on such effects. (Author/SAH)

Visual representations are essential for communicating ideas in the science classroom; however, the design of such representations is not always beneficial for learners. This paper presents instructional design considerations providing empirical evidence and integrating theoretical concepts related to cognitive load. Learners have a limited…

Most research on personal epistemologies has conceived them as made up of relatively large, coherent, and stable cognitive structures, either developmental stages or beliefs (perhaps organized into theories). Recent work has challenged these views, arguing that personal epistemologies are better understood as made up of finer grained cognitive…

Reviews conceptions of culture and language to provide a conceptual framework for understanding the ways in which cultural differences between students and science teachers can influence science education. Examines theoretical and practical implications of this issue. (KH)

Describes the use of Moe's Mall, a locational device designed to be used by learners, as a simple algorithm for solving mole-based exercises efficiently and accurately using dimensional analysis. (DDR)

Identifies the types of questions that students ask during science learning. Explicates the role of students' questions in the knowledge construction process, particularly in educational discourse. Investigates the relationship between students' questions and approaches to learning and discusses some emergent issues related to student questioning.…

Presented are the results of a study of high school and college students concerning their thinking about functions of the human body. It was shown that students' thinking could be positively changed over the short term from teleologic to mechanistic. Sample survey questions are included. (CW)

Given that enhancing the motivation of young people for science is a widely shared goal, the question posed is how to raise intellectual satisfaction among students by showing the consistency and conciseness of physical theories. I argue that certain rituals in our teaching practices can make physical theories seem inconsistent, even absurd. Using…

This project addressed the question: What knowledge and processes enable individuals to construct and modify representations of novel, nonroutine problems? The theoretical goal was to extend the information-processing theory of problem solving to include processes that have been characterized as restructuring of problems and productive thinking by…
